Contract Killer: Zombies has received rather mix criticism from fans of the contract killer series and one of the most ongoing discussions in recent reviews is that reviewers are demanding a change to the pricing of the in-game guns however this request has fallen on deaf ears and continues to leave the game as it is with no further plans to change gun prices nor double in-game payment upon completing missions.

The App Store currently rates the game at 4 stars making it a good game.
